台灣地處亞熱帶,高溫溼熱,且雨季綿長,在這樣的天候狀況下,落
於道路上之雨水若不易迅速排除,而於鋪面表層形成積水的現象,則當車
輛快速通過時,往往造成水花四濺,更由於水膜的存在會使得路面的抗滑
性大幅降低,嚴重影響行車的視界與安全性。 目前北二高與中山高
速公路部分路段,均有採用表面加鋪1.5 cm開放級配的方式,但是效果均
不太理想;故本文擬採用歐洲之多孔性瀝青混凝土(Porous Asphalt)鋪面
之級配為基礎,配合上纖維與石灰作為添加劑與防剝劑,並採用AC-20 與
數種改質瀝青作為黏結劑,進行多孔性瀝青混凝土的最佳配比研究。
本研究中之多孔性瀝青混凝土配合設計方法,包括瀝青分離流失試驗與
Cantabrian磨耗試驗等,用以決定此多孔性瀝青混凝土的最佳含油量範圍
;而後以旋轉剪力壓實機(GTM)製作試體,進行回彈模數、間接張力等力
學性質試驗;另以紫外線與加壓氧化老化兩種 方式,並配合人工養治櫃
,對於此多孔隙之瀝青混凝土的耐久性進行評估:此外,對於多孔性瀝青
混凝土最為重要之透水性與抗滑性、抗車轍能力等,亦均以實驗室中可用
之方法進行試驗評估。
研究結果顯示,在配合設計過程中,以AC20瀝青添加纖維所製成之瀝青
混凝土,確實可有效降低瀝青流失量,但在Cantabrian磨耗試驗中,仍是
以使用改質瀝青之改善效果較為明顯;而在各項力學性質與成效試驗上,
均是多孔性級配瀝青混凝土優於開放級配,尤其在透水係數試驗上,多孔
性級配甚至高出開放級配三倍以上。由此可知,多孔性瀝青混凝土確實應
較目前所使用之開放級配瀝青混凝土,更適合台灣此一多雨的環境。
Due to the subtropical situation of Taiwan, not only is the
weather here hot and humid, but the monsoon is quite long.
Under the circumstances if the Pavement cannot drain the
rainwater rapidly, the water will splash and the skid
resistance of pavement will be reduced owing to water film when
the vehicle pass quickly, which may severely affect the
driver''s sight and security.
Now part of the Sun Yat-sen Freeway and Second Northern Freeway
are pavedwith a layer of 1.5cm open grading; however, the effect
is not desirable. Therefore, here we are trying to research
on the optimal design method of porous asphalt based on the
grading of European Porous Asphalt along with thefiber and lime
as addition and anti-stripping agent. We also adopt AC-20 and
other several modified asphalt as binder.
The design method of porous asphalt in this research, including
the Asphalt Adhesion Test and Cantabrian Abrasion Test and
so on, has determined the optimal asphalt content. The test
specimens are made by Gyratory Testing Machine (GTM). Its
mechanical properties are evaluated by Resilient Modulus,
Indirect Tensile Test, etc. In addition, we evaluate the
durability of porous asphalt in Ultraviolet Chamber and by
Pressure Oxidation Vessel. As to the resistance to
deformation, the skid resistance, and the draining capacity of
porous asphalt, they can all be evaluated by usable methods in
our laboratory. From the results of the research, the AC-20
asphalt mixture made with fiber does reduce the lost of
asphalt effectively during the process of this design method.
However, the effect of the modified asphalt is still more
obvious in the Cantabrian Abrasion Test. As to all mechanical
properties test,porous asphalt overweighs open-grading,
particularly in Permeability Coefficient Test, the
permeability of porous asphalt is even triple the open-
grading. As a result, in the rainy environment of Taiwan, porous
asphalt should have great value in practical use.
